Determination of optical properties and thickness of optical thin film using stochastic particle swarm optimization

We report on the development of Ni-shielded ZnO nanorod (NR) structures and the impact of the Ni layer on the ZnO NR properties. We developed nickel-capped zinc oxide nanorod (ZnO/Ni NR) structures by e-beam evaporation of Ni and the subsequent annealing of the ZnO/Ni core/shell nanostructures. The core/shell NRs annealed at 400 °C showed superior crystalline and emission properties. More interestingly, with the increase of annealing temperature, the crystallinity of the Ni shells over the ZnO NRs gradually changed from polycrystalline to single crystalline. The presence of the Ni layer as a polycrystalline shell completely hindered the light emission and transmission of the ZnO NR cores. Further, the band gap of ZnO NRs continuously decreased with the increase of annealing temperature.

Zinc Oxide Nanorods Shielded with an Ultrathin Nickel Layer: Tailoring of Physical Properties

The invention discloses a flexible transparent silver grid composite electrode and a production method thereof. The electrode structure is as follows: A/ a silver grid/ an elastic substrate. The A can be conductive polymer (PEDOT:PSS), a metal-oxide-semiconductor (ZnO), and a binary complex of the above mentioned materials. The substrate adopts high elasticity plastics, such as polyethylene terephthalate (PET), polyimide (PI), polyvinylalcohol (PVA), polydimethylsiloxane (PDMS), polyurethane acrylate(PUA), and hydrogel, and so on. The production method is characterized in that the metal grid and the A material are sequentially printed on the high elasticity plastic substrate by adopting the ink-jet printing technology. The produced transparent electrode is advantageous in that the comprehensive performance is excellent, the square resistance is low, the flexibility is good (the electrode can be bent, distorted, and even stretched at will), the surface is leveled, the oxidation-resistant capability is strong, and the shape and the size can be adjusted at will.
